How does religion explain birth defects?

[Lethe]

@ Skipper why does evolution allow for birth defects in humans, what possible purpose do these awful birth defects serve in evolution? Is evolution on the hunt for the perfect human or might it be that evolution is nothing more than random acts with no real purpose at all? With humans and apes sharing 98% of there DNA why is it that these types of birth defects do not show up in the apes very often?

The video in post #48 explains this fairly well.

Since a lot of evolutionist and even some on this site believe that in the grand scheme of things, humans have no more value than any other animal, why don't we just kill the defective babies and rid our species of these terrible traits?

No more value in the eyes of some unseen creator, yes, many do, but obviously it is natural to attribute more value to members of your own species than non-members. And mothers don't kill their defective babies for numerous reasons. A maternal bond being one of the more powerful deterrents, which has obvious advantages evolutionarily speaking.

Why has evolution left us with such a weakness as to feel a survival connection to such deformed animals which places a burden on the society as a whole?

The advantages of compassion outweigh the disadvantages. Social cohesion has been vital to humans' success, and one of the ways in which this was achieved was through the development of such traits as empathy and the ability to form strong emotional ties.

Why should I have to pay out taxes to help keep such defective people up when the rest of the animal kingdom rids themselves of this problem.

Except not all other animals do. Many animals, mammals in particular, care and provide for their young, old, feeble, and disabled. Elephants would be just one example.

Why are my tax dollars wasted on studies of these defects because evolution left the human race without the sense to rid itself of defective babies? Just wanting to know how you and other nonbelievers felt about this?

Again, because the evolutionary benefits of acquiring compassion ultimately outweigh the disadvantages.
